SUPER MAXBIT
Multifunctional simultaneous casing drilling system that realizes stable drilling with less hole bending by 2 to 3 blades installed at the tip of the device.
The SUPER MAXBIT, which features a bit head positioned at the tip of the device that can expand or contract in bit diameter by rotating it forward or in reverse, allows for stable excavation in any collapsible ground by following the casing.

Features
SUPER MAXBIT
The SUPER MAXBIT gives stability when drilling collapsing overburden formations.
This is an advanced technology compared to the other eccentric drilling methods. It consists of two to three wings connected to the Down The Hole Hammer. The bit wings can be opened/retracted in forward/backward rotation.
Drilling and casing installation are possible simultaneously with the use of a casing shoe.
The SUPER MAXBIT has a following advantages:
・High-speed drilling similar to a standard DTH bit.
・Straight hole drilling.
・Uniform rotation while drilling of boulders, sand and gravel.
・Reliability of extending and retracting proven by customer experiences.
Mechanism
The SUPER MAXBIT is composed of the following mechanisms.
SUPER MAXBIT G-MOGEL
The SUPER MAXBIT G-MOGEL is equipped with two or three wings on the same body as the SUPER MAXBIT, and the tungsten carbide tips mounted on the device deliver excellent drilling performance in hard rock formations.
In addition, the bit head features an independent opening/closing and diameter-reducing mechanism, enabling easy and stable reaming operations.
The design also allows for a large reaming diameter, making it suitable for use with thick-walled steel pipes.
Applications
The Casing Advanced System is used for various applications when combined with an appropriate drill rig and either DTH hammers or top hammers.
Water Well
Drilling water wells down to 50-250m in depth.
Piling
Casing pipes are driven simultaneously while drilling through the collapsing overburden. After that, H‑steel beams are installed, and then the casing pipes are pulled out.
Foundation
SUPER MAXBIT is capable of installing casing pipes up to 32 inches in diameter (Ø800 mm) for foundation construction of buildings and bridges.
Pipe Roof, Water Service
Drainage construction, Anchoring
SUPER MAXBIT achives excellent results for drilling of long holes through overburden including hard rocks by using with the Down The Hole Hammer.
Top-Hammer applications are also available for pipe roofing in Tunnel construction.
Geothermal, Oil Well
SUPER MAXBIT is used for drilling and casing operations down to depths of up to 50 meters for geothermal and oil well construction.
